Something wrong

[Damo-bar]

My first attempt at brewing had great advice of here but my worry is that my yeast maybe dead it was in garage with warm belt on but worries it wasn’t warm enough as it was freezing inside garage so thought I’d bring it in it’s not bubbling much and temp on outside bucket is 18 temp of brew (took a sample ) is 7 is it game over or shall I just believe and which thermometer should I go with thank you

I have many times in early days allowed brew to cool too much, and it has stalled, but once warm again all has been OK.

At 7° I think the yeast is probably just went dormant. Now that you have bought it inside, as ericmark has suggested above, and the brew warms up it will wake up and fermentation will re-commence. As for thermometers I would look at something like the inkbird 308 you can control your heat belt and later on if you end up with a fermentation fridge you can also use it for cooling.
